SPECIFICATION formingpart of Letters Patent No. 735,534, dated August 4,1903. Application filed September 16, 1902. 3 Serial No. 123,565. (Nomodel.)

To aZZ whom it may concern:

Be it known that we, MARK P. LAYTON and JAMES W. VAN DOREN, citizens ofthe United States, and both residents of Minonk, in the county ofWoodford and State oflllinois,have invented a new and Improved Derailer,of

which the following is a full, clear, and exact description.

This invention relates to a device for running railway rolling-stockfrom the rails. It is applicable in various connections, particularly onsidings or switches, so as to prevent the cars on the switch from beingrun back accidentally onto the main track.

One of the prime features of our invention lies in the entire automaticaction of the derailer. Assuming that it be placed on a sid ing orswitch, as cars are entered into the siding the derailer will notinterfere therewith, but will automatically give way. Should, however,the cars be started in the opposite directionthat is to say, toward themain trackthe derailer will throw the cars from the Siding and preventthem from reaching the main rails.

The construction of the derailer is such that it may be moved fromactive into inactive position by the railway men whenever desired, andwhen so moved it will have no action upon the cars, no matter whetherthey-be running into or out of the siding.

This specification is an exact description of one example of ourinvention,while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of the invention. Fig. 2 is a plan viewthereof. Fig. 3. is a section on the line 3 3 of Fig. 2, and Fig.

4 is a side View showing the derailer in inop-- erative position.

The device comprises a base-plate a, which is arranged to be fastened tothe ties in the manner shown in Figs. 1 and 2 or in any other suitablemanner. On this base-plate is formed a slideway ct, which is disposedslightly diagonally with respect to the rail. In this slideway isarranged a slide 19, which has a stem 1) fitted in the slideway and aspring a pressing the stem, so as to hold the slide the rail.

yieldingly in the active position shown in the drawings. The slideway ahas a raised or beaded portion a atthe top thereof, as best shown inFigs. 3 and 4, the stem 1 and spring 0 being received in a cavity formedin the slideway.

01 indicates the derailing-plate,which is connected by a hinge d withthe slide 1) and which is normally adapted to lie over the bead a and toextend inward over the ball of The said plate at hasdownwardlyprojecting side flanges (1 which inclose the bead a and bythis engagement of the parts d and a lateral movement of the plate (1.is prevented and undue strain on the hinge d is avoided. At its free endthe derailing plate d is formedwith an upwardly and outwardlyinclinedsurface d adapted to bear the tread of the wheel, and acorrespondinglydisposed surface 01 adapted to engage the flange of thewheel, so that should the car advance toward the derailer'in thedirection ofthe arrow min Fig. 2 the wheel will ride up the surfaces 01and d and be derailed. If, however, the car should approach the devicein the direction of thearrow y, the outer side of the wheel will rideagainst the curved inner edge or face (1 of the plate (1 and push saidplate outward against the tension of the spring 0, thus allowing the carto pass the derailer without disturbing the proper engagementof thewheels with the raileindicates a pin which is passed through a boss at,formed on one of the flanges d of the plate at and surrounding anopening in said flange, so that said pin 6 may engage in a slot a formedin the bead a and disposed longitudinally thereof. This slot limits themovement of the plate d, but allows it to assume the operativepositiontshown in Fig. 2) or the inoperative position, in which saidplate is pushed sidewise to allow the wheel to pass. The tube or boss 01is formed with two opposite openings d", one of which is shown in Fig.4, and through these openings is adapted to be passed the hasp of alock. (Indicated atfin Figs. 1 and 2-.) This lock is also engaged withthe pin 6, and by these means the pin may be held in place and removedonly by releasing the lock f. 9 indicates a chain or the like forfastening the pin e to one of the ties, so as to-prevent the accidentalloss of the pin. When the pin a is withdrawn, the plate (I may be thrownoutward from the position shown in Fig. 2 to that shown in Fig. 4, inwhich position it will be wholly inactive.

In the use of the invention, assuming that it were applied to a sidingin such a manner as to allow cars to be entered thereinto, but toprevent them from being accidentally moved off of the siding, thederailer should be arranged so that the cars in entering into the sidingwill move in the direction of the arrow y in Fig. 2. Thus it will beseen that any number of cars may be pushed onto the siding withoutinterference by the derailer. Should, however, any of the cars beaccidentally moved ot't of the siding in the direction of the arrow 0:in Fig. 2, if the cars are moving with sufiicient velocity the wheelswill ride up the surfaces 01 and d and be entirely derailed. However,should the cars be moved at a low speedfor example, should a high windcause the cars to move-as thewheels strike the inclined surfaces 61 andd the movement of the cars will be arrested, and the derailer will thenact as a bumper or stop. When the cars are to be intentionally removedfrom the siding, the railwayman in charge should release the lockfandremove the pin e. The derailing-plate cl may then be thrown out, asshown in Fig. 4, and the cars passed to and fro irrespective of thederailer.

Various changes in the form, proportions, and minor details of ourinvention may be resorted to at will without departing from the spiritand scope thereof. Hence we consider ourselves entitled to all suchvariations as may lie within the intent of our claims.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination of a base, a slide thereon,a derailing member mounted to move with and on the slide, and meanspressing the slide to hold the derailing member normally in activeposition.

2. The combination of a base, a slide thereon, aderailing member mountedto move with and on the slide, and means pressing the slide to hold thederailing member normally in active position, said derailing memberhaving a face or edge disposed diagonally with respect to thelongitudinal line of the rail.

3. Thecombinationofabasehavingaslideway thereon and anupwardly-projected bead, a slide mounted in the slideway, a springpressing the slide, and a derailingplate hingedly mounted on the slideand normally bearing on the head.

4. The combination ofa base havinga slide- Way thereon and anupwardly-projected bead, a slide mounted in the slideway, a springpressing the slide, a derailing-plate hingedly mounted on the slide andnormally bearing on the bead, means for limiting the sliding movement ofthe derailing-plate, and a lock for releasably holding said means inactive position.

5. The combination of abase,a slide mounted thereon, means pressing theslide into active position, and a derailing member mounted on the slideto move therewith and to move independently thereof.

6. In a derailer, the combination of a base, a derailing member, meansfor mounting the derailing member to slide on the base toward and fromthe rail, and means yieldingly holding said derailing member normallyinto active position, the derailing member comprising a face normallyextending diagonally across the ball of the rail, for the purposespecified.

7. The combination of a base having a slot therein, a slide mounted onthe base, a derailing member mounted to move with and on the slide, andmeans carried on the derailing member and coacting with the walls ofsaid slot for the purpose specified.

8. The combination of a base having a slot therein, a slide mounted onthe base, a derailing member mounted to move with and on the slide, andmeans carried on the derailing member and coacting with the walls ofsaid slot for the purpose specified, said means comprising a boss on thederailing member, a pin fitted loosely in the boss and running in theslot, and means for holding the pin removably in place.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
